Description
Technical Field

Background
In the field of central air conditioning, the thermal comfort of the end user is often one of the important indicators used to assess whether a central air conditioning system function is being effectively implemented. The term "thermal comfort" refers to the subjective and objective evaluation of a human body to satisfy the hot and humid environment. Thermal comfort is whether a human body feels comfortable or not through the combination of thermal balance and sensed environmental conditions, which is determined by the combination of physiology and psychology, and is more emphasized on psychology, and environmental parameters influencing the thermal comfort of the human body mainly comprise air temperature, air flow speed, air humidity and average radiation temperature; the human parameters include thermal resistance of the clothes and labor intensity. The research on human thermal comfort relates to the disciplines of building thermophysics, physiology of human thermal regulation mechanism, human psychology and the like. More than 80% of the life of a person spends indoors, and the quality of indoor environment such as sound, light and heat environment and the quality of indoor air directly affect the physical and psychological health, comfort and working efficiency of the person. Meanwhile, a large number of domestic and foreign studies indicate that the indoor air quality is also related to the thermal environment: 1) the air temperature, humidity and wind speed can affect the release of indoor pollutants; 2) the sensation of pollutants is temperature dependent, and foreign research suggests that a decrease in temperature may be more comfortable and less unsatisfactory for air quality, while the chemical composition of the indoor air remains unchanged. To achieve a comfortable thermal environment, countries consume large amounts of energy for heating and air conditioning each year. Aiming at the air quality requirements of inpatients in sickrooms of hospital institutions, a traditional hospital air conditioning system usually adopts a constant temperature control method, only carries out real-time monitoring and fixed temperature value adjustment setting on the temperature of air dry balls in spaces, neglects the urgent requirements of the persons (such as old, weak, sick, disabled and pregnant) in the spaces on cold and hot sensing, dryness and humidity and air freshness, and possibly aggravates the illness state or discomfort of waiting staff.
